Other then ascending (though not monotonically), idx appears to have no real value to user space. I see in the rfkill driver where its being assigned, and it appears to be an rfkill instance number that describes a relationship to a device. For example: Here is the output before toggling and right after a boot: rtg@xps1330:~$ ./rfkill bluetooth 0 UNBLOCKED soft:0 hard:0 wlan 1 UNBLOCKED soft:0 hard:0 bluetooth 2 UNBLOCKED soft:0 hard:0 wlan 3 UNBLOCKED soft:0 hard:0 UNBLOCKED After toggling to BLOCKED: rtg@xps1330:~$ sudo ./rfkill 1 [sudo] password for rtg: rtg@xps1330:~$ ./rfkill wlan 1 SOFT_BLOCKED soft:1 hard:0 bluetooth 2 SOFT_BLOCKED soft:1 hard:0 wlan 3 HARD_BLOCKED soft:1 hard:1 BLOCKED After toggling to UNBLOCKED: rtg@xps1330:~$ sudo ./rfkill 0 rtg@xps1330:~$ ./rfkill wlan 1 HARD_BLOCKED soft:0 hard:1 bluetooth 2 HARD_BLOCKED soft:0 hard:1 wlan 3 UNBLOCKED soft:0 hard:0 bluetooth 4 UNBLOCKED soft:0 hard:0 UNBLOCKED This laptop only has one wlan and one bluetooth device. Why the extra index values? rtg -- Tim Gardner tim.gardner@canonical.com
